The Washington Post report claimed that, “In early 2011, then-CIA Director Leon Panetta confronted the president of Pakistan with a disturbing piece of intelligence. The spy agency had learned that ­Mohammad Omar, the Taliban leader who had become one of the world’s most wanted fugitives after the Sept. 11, 2001, attacks, was being treated at a hospital in Karachi.

The report added that, “The American spy chief even identified the facility — the Aga Khan University Hospital in Karachi — and said the CIA had “some raw intelligence on this” that would soon be shared with its Pakistani counterpart”.

Taliban supremo Mullah Omar died two years ago in Pakistan, Afghanistan said on Wednesday, after unnamed government and militant sources reported the demise of the reclusive warrior-cleric.
